Extended Data Fig. 8. Analysis of the periarteriolar MC phenotype in situ.

Extended Data Fig. 8

(a) Representative visualization of Mcpt6 mRNA using fluorescence in situ hybridization (FISH) in ear skin whole mount tissue of adult WT mice. These data refer to the post-imaging analysis of Mcpt6 expression in periarteriolar versus interstitial MCs in Fig. 4i,j. Representative image from one of n = 4 mice. (b) Differential expression of MCPT6 in periarteriolar versus interstitial MCs. Ear skin whole mount tissue of an adult WT mouse is counter-stained for the pan-MC marker avidin (cyan), MCPT6 (green), COL4-expressing basement membranes (red) and ACTA2-positive arterioles (white). Avidin and MCPT6 fluorescence intensities are also displayed as heatmap. (c,d) Imaris software-based workflows for the post-imaging analysis of MCPT6 mean fluorescence intensities in MC subsets (c) and calculation of the percentage of MCPT6high MCs of all periarteriolar MCs in WT and Tln1ΔMC mice (d). (b-d) Representative images from one experiment of n = 5 mice. Scale bars: 50 µm (a, d), and 100 µm (b,c).
